ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor
Sensor Pixel Array
Image Flow Processor
Image and color processing in the ASX340AT are implemented as an image flow
processor (IFP) coded in hardware logic. During normal operation, the embedded
microcontroller will automatically adjust the operation parameters. The IFP is broken
down into different sections, as outlined in Figure 9.
